CARRIAGE-AXLE WASHER.

SPECIFICATION forming part of Letters Patent No. 349,593, dated September 21, 1886. Application filed June 4, 1886. Serial No. 204,175. (No model.)

To all whom it mayconcern:

Be itknown that I, DANIEL A. JOHNSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Carriage-Axle XVashers, of which the following, taken in conuection with the accompanying drawings, is a specification.

The object of my invention is to produce a carriage-axle spring-washer, of suitable material, that will be effective and durable in use,

easily and cheaply manufactured, and correct in its action.

Myinvention relates to carriage-axle springwashers designed as an improvement of the sp ring-washers shown and described in United States Letters Patent No. 330, 4.92, granted to me November 17, 1885; and it has forits object the more economical production of a carriage-axle washer that will be more effective, reliable, and durable.

Figure 1 represents in plan and elevation a carriage-axle spring-washer blank. represents in side elevation and plan a carriage l axle washer. Fig, 3 represents in side elevation and plan a stop; and Fig. 4 represents in side elevation and plan a washer, both stop and washer being used in connection with a carriage-axle and a carriageaxle springwasher. Fig. 5 represents in side elevation a carriage-axle with the stop. Fig. 6 represents in side elevation a carriage-axle, and in partial section a carriage-axle box and nut-stop and the carriage-axle spring-washer on oneend of the carriage-axle, and on the otherend aleather washer carriage-axle springwasher and a plain washer. Fig. 7 represents, by dotted lines and in elevation, all the parts shown in Fig. 5.

In the manufacture and sale of spring-washers made in accordance with my said Letters Patent No. 330,492, obstacles were found that to some extent prevented their sale. The said spring-washers being constructed in pieces and riveted, made them cost too much; and by using rivets it was found in the use of the springwashers that the rivets would become loose, and thereby out both axle and axle-box. These obstacles are entirely overcome in my invention.

The blank 10, Fig. 1, represents a dropforging or plate metal made to dimensions in Fig. 2'

the usual manner. It is then folded, compressed, punched, and trimmed. Then it is ready for use, afterbeing tempered, if necessary, as a earri'ageaxle spring-washer. (Designated in Fig. 2 by 11.)

The stop 12 is made as shown in Fig. 3, and cut so that its diameter can be increased or diminished, as required. It is used on the carriage-axle 16 for the purpose of making a stop for the nut 14, so as to leave a suitable space for the spring-washer 11 to perform its duties as a spring between the nut 14 and the axlebox 15, so as to ease the blow and prevent the noise which might otherwise be caused by the lateral movement of the axle-box 15 when in use as an axle-box for a carriage-wheel. The stop is cut or split, so that it maybe compressed or expanded so as to fit over the threaded end of the axle over which it is used.

WVhen axles are made so that the turned portion of the axle extends beyond the axle-box to the threaded portion to a length equal to the width of the space required for the proper. action of the spring-washer, as previously stated, then no stop is required. The use of the stop is only required on axles notrmade for the use of my spring-washer. The plain washer 13 is used in connection with the leather washer 17 whenever there is more than sufficient space between the end 18 of the axle-box and the collar 19 of the axle for the proper and correct working of the spring-washer. Their use is necessitated to prevent the rattle of the axlebox end 18 against the axle-collar 19, caused in use by the reaction ofthe spring-washer.

W'hen axles and axleboxes are made to give the correct required space between the said turned portion of the axle and the axle-nut, and between the end 18 of the axle andthe axle-collar 19, then the stop, plain washer, and leather washer are not needed, and the use of them is necessitated on axles that are not made so that the spring-washers may be used.

By reason of its construction my carriageaxle washer presents for wear parallel (or nearly so) bearing-surfaces. It also, by reason of its simple and economical construction, permits its introduction in competition with leather washers, which are in common use.

WVhat I claim and desire to secure by Letters Patent is 1. A carriage-axle V-shaped spring-washer,

in combination with a carriage-axle and box, 4. A carriage-axle having the box held latsubstantially as described. erall y between V-shaped spring-Washers, sub- 2. A carriage-axle V-shaped spring-washer, stantially as described. in combination with a carriage-axle and box, In testimony whereof I have signed my name I 5 5 stop 12, leather washer 17, and washer 13, to this specification, in the presence of two subsubstantially as described. scribing witnesses, 011 this 1st day of June,
